It harvests host and local system-file data, then sends it to an unrelated external host. - **Trigger:** npm install or any install action that runs the preinstall lifecycle hook. - **Impact:** Exposure of username, hostname, home/install paths, DNS configuration, and contents of /etc/passwd and /etc/hosts. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-07-23T11:55:19.076Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time host fingerprinting and data exfiltration via HTTPS POST - **Attack narrative:** Installation invokes package-controlled index.js through preinstall. The script gathers host identity and network configuration, reads /etc/passwd and /etc/hosts if available, serializes the data, and POSTs it to mka6p95xmnkfcmdxv8cb4h2rpivej47t.oastify.com. This is unconsented install-time data exfiltration. - **Rationale:** Direct source inspection confirms an automatic preinstall hook performing local-file and host-data exfiltration to an external OAST endpoint. This is concrete malicious behavior, not merely a suspicious primitive. - **Files touched:** package.json, index.js, /etc/passwd, /etc/hosts - **Network endpoints:** mka6p95xmnkfcmdxv8cb4h2rpivej47t.oastify.com ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs \`node index.js\` in preinstall., index.js collects home path, hostname, username, and DNS servers., index.js reads /etc/passwd and /etc/hosts when present., index.js POSTs collected data to an external OAST host during installation. ## Public findings ### 1.
